Pressurizing equipment, using method thereof and formed lubricating system

The invention discloses pressurizing equipment, a using method thereof and a formed lubricating system. The equipment is composed of a plurality of pressurizers arranged on a canvas conveying pipe; each pressurizer is composed of a positive pressure bag and a negative pressure bag, wherein the positive pressure bag is located at the front end of the negative pressure bag, a pump is arranged in the positive pressure bag and contains a lubricating agent, a positive pressure cavity is formed by the contact face of the positive pressure bag and the canvas conveying pipe, and a negative pressure cavity is formed by the contact face of the negative pressure bag and the canvas conveying pipe; the lubricating agents are released by the pumps and flow into the positive pressure cavities, the positive pressure cavities press the lubricating agents into the canvas conveying pipe under the pressure effect, the negative pressure cavities suck the lubricating agents, and a section of lubricating film wrapping a conveying b
